TrueChain (TRUE) is developing a public blockchain for real commercial decentralized applications. The blockchain is based on an improved PBFT consensus protocol that provides fast peer-to-peer communication, value transfer, and efficient smart contract infrastructure. It is starting with digital advertising industry D-applications, but prepared for supporting all commercial D-applications too. As the needs for performance-demanding commercial Dapps emerge, TrueChain aims to become the next-generation public chain for commercial applications. It not only provides protocol for faster digital asset transfer, it breaks some limitations of PBFT blockchains and implements CsC (consensus contract) for a strong development team & community globally.
